TE Connectivity 104427-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 104427-4 is a rectangular connector header classified as a vertical through-hole component with 6 positions at 2.54mm pitch. This connector belongs to the AMPMODU Mod II series and features male pin contacts with press-fit and solder termination options. The part is currently obsolete, necessitating identification of active equivalent and substitute components that maintain functional compatibility for board-to-board applications. Substitute parts must satisfy the core electrical and mechanical parameters: 6-position configuration, 0.100" (2.54mm) pitch, through-hole mounting, male pin contacts, and equivalent current and voltage ratings.

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the TE Connectivity 104427-4 based on critical electrical and mechanical parameters. Selection among these alternatives should be guided by the following factors:

Product Status and Availability: All substitute parts maintain active product status with Amphenol ICC (FCI), ensuring ongoing availability and supply chain continuity. The original 104427-4 is obsolete and no longer manufactured.

RoHS Compliance Considerations: The original 104427-4 is RoHS non-compliant. For applications requiring RoHS compliance, the following substitute parts are certified RoHS Compliant:

77311-122-06LF
77311-146-06LF
77311-422-06LF
77311-446-06LF
77311-822-06LF
78229-206HTLF
78511-206HLF

For applications with no RoHS requirement, RoHS non-compliant alternatives remain functionally equivalent:

54101-S30-06
68457-406
78229-206

Operating Temperature Range: The original 104427-4 operates from -65°C to 105°C. Substitute parts offering extended operating range (-65°C to 125°C) provide additional thermal margin:

77311-122-06LF
77311-146-06LF
77311-422-06LF
77311-446-06LF
77311-822-06LF
78511-206HLF

Current Rating: The original 104427-4 is rated at 3A. The substitute part 78511-206HLF provides enhanced current capacity at 5A per contact, suitable for higher-power applications while maintaining all other compatibility parameters.

Termination Method: The original 104427-4 supports both Press-Fit and Solder termination. Substitute parts offering identical dual termination capability:

78229-206
78229-206HTLF

Solder-only termination alternatives are available in all other listed parts.

Contact Finish Options: Gold-plated contact finishes are available in most substitute parts, matching the original 104427-4 specification. Tin-plated alternatives (68457-406, 77311-422-06LF, 77311-446-06LF) provide cost-effective substitution for applications where gold plating is not required.

Packaging Considerations: Substitute parts are available in multiple packaging formats (Bulk, Bag, Tube) to accommodate different procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the TE Connectivity 104427-4 with any of the listed Amphenol ICC (FCI) parts?

A: Yes. All listed substitute parts are electrically and mechanically compatible with the 104427-4. They share identical critical parameters: 6-position configuration, 0.100" (2.54mm) pitch, through-hole mounting, male pin contacts, square contact shape, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. Physical board layout and mating interface compatibility are maintained across all substitutes.

Q: What is the difference between BERGSTIK® and BERGSTIK® II series connectors?

A: Both series are manufactured by Amphenol ICC (FCI) and are functionally equivalent for the 6-position 2.54mm pitch header application. BERGSTIK® II represents a newer product line with enhanced design features. For the 104427-4 replacement application, either series provides equivalent electrical and mechanical performance. Selection may be based on packaging preference, availability, or RoHS compliance requirements.

Q: Are there differences in contact finish between substitute parts?

A: Yes. The original 104427-4 features gold-plated mating contacts with 15.0µin (0.38µm) thickness. Substitute parts offer three contact finish options: Gold (15.0µin or 30.0µin thickness), Gold with GXT™ coating, or Tin (78.7µin or 100.0µin thickness). Gold finishes provide superior corrosion resistance and are recommended for applications with stringent reliability requirements. Tin finishes are suitable for standard industrial applications and offer cost advantages.

Q: Which substitute part should I select if RoHS compliance is required?

A: For RoHS-compliant applications, select from: 77311-122-06LF, 77311-146-06LF, 77311-422-06LF, 77311-446-06LF, 77311-822-06LF, 78229-206HTLF, or 78511-206HLF. All other listed parts are RoHS non-compliant.

Q: What is the difference between Press-Fit and Solder termination?

A: Press-Fit termination allows the connector to be inserted into plated through-holes without soldering, providing faster assembly and reduced thermal stress on components. Solder termination requires traditional wave or reflow soldering. The original 104427-4 supports both methods. Substitute parts 78229-206 and 78229-206HTLF also support dual termination. All other substitutes support solder termination only. Selection depends on assembly process capability and PCB design.

Q: Can I use a substitute part with a higher current rating than the original 104427-4?

A: Yes. The substitute part 78511-206HLF is rated at 5A per contact, compared to the original 3A rating. Using a higher-rated component does not create compatibility issues and provides additional current capacity margin for applications requiring increased power handling.

Q: What is the significance of the insulation height difference between the 104427-4 and substitute parts?

A: The original 104427-4 has an insulation height of 0.090" (2.29mm), while most substitute parts specify 0.100" (2.54mm). This minor dimensional difference does not affect electrical compatibility or mating interface function. The slightly taller insulation in substitute parts provides equivalent or improved mechanical stability. PCB layout and connector cavity dimensions should be verified for specific applications.

Q: Are there inventory considerations when selecting a substitute part?

A: Yes. Inventory levels vary among substitute parts. Parts with higher inventory availability (such as 77311-146-06LF with 1015 units and 78511-206HLF with 3541 units) may offer faster delivery and reduced supply chain risk compared to parts with lower stock levels.

Q: What packaging options are available for substitute parts?

A: Substitute parts are supplied in three packaging formats: Bulk (loose components), Bag (bagged quantities), and Tube (tubed quantities). Packaging selection should align with assembly process requirements and inventory management practices. Bulk packaging is suitable for high-volume production, while Bag and Tube packaging accommodate smaller lot sizes and component handling preferences.

Q: Is the contact material difference (Copper Alloy vs. Phosphor Bronze) significant?

A: The original 104427-4 uses Copper Alloy contacts, while all substitute parts use Phosphor Bronze. Phosphor Bronze provides superior spring properties, wear resistance, and contact reliability. This material change represents an improvement over the original specification and does not create compatibility issues. Phosphor Bronze is the industry standard for high-reliability connector applications.
